Abstract
A folding foot step of the type used on vehicles has an improved anti-skid, friction grip, stand-on surface with a clover-leaflet-shaped perimeter. The stand-on surface is interrupted by three elongate openings that are spaced inwardly from the perimeter and arrayed to extend about an uninterrupted central region of the stand-on surface. An upwardly-opening recess is defined by a narrow upstanding rim that runs along and defines the perimeter of the stand-on surface, and by narrow upstanding rims that encircle the three openings. Anti-skid material is nested in the recess, covers the floor of the recess, and cooperates with the narrow upstanding rims to provide a stand-on surface that features a friction-grip texture in the central region and in regions of the stand-on surface located between the openings, and between the openings and the perimeter
